Cylinder Deactivation
is this technology will be introduced in our future GL, or else as a mod for current ones. which may save some money on current day gas prices.

I don't think it would work that well with diesel for ignition and compression reasons. As for gas, the savings are likely not worth the effort would be my guess.

Dodge 3500 diesel, Jeep Commander
I've got cylinder deactivation in my Jeep Commander Overland, and I don't think its practical. I get dismal mileage anyway, about 15 mpg max, and when more power is needed, and the other 4 cylinders cut in, there is a surge that sometimes spins the tires (and thats hard to do with full-time 4x4 drive). I've seen this system used in Cadillac and it seemed to have the same issues, and the dismal mileage! MB gets even more horsepower from their V8 with none of that extra complexity, and a lot better mileage.
The Overland has a 5 speed automatic, which works well, but still poor mileage.
I don't think this system would work on a diesel very well due to the extreme pressures involved. I think VW tested this on their diesels at one time, but it never made it to production, at least that I know of.
